In Securities and Exchange Commission filings it made Monday, Columbia Management, which does business as Columbia Threadneedle Investments, is also seeking permission from regulators to launch index-based exchange-traded funds, a product it doesn’t currently offer.

“We filed for exemptive relief as we consider multiple and complementary product options," Columbia Threadneedle said in an emailed statement.

It declined to comment further on the filings.

Eaton Vance has said it plans to launch exchange-traded managed funds later this year. The planned ETMFs, which Eaton Vance has dubbed NextShares, will have some characteristics of mutual funds and some characteristics of exchange-traded funds.

ETMFs will be actively managed and traded on an exchange like ETFs. But they won’t be required to reveal their holdings as frequently as ETFs. That is expected to attract active fund managers who have eschewed managing active ETFs for fear that frequent disclosure would expose their funds to front-running risk.

Stephen Clarke, president of Navigate Fund Solutions, a subsidiary of Eaton Vance and the sponsor of NextShares, said, "We are delighted to welcome Columbia Threadneedle as a NextShares licensee.”
